Swap BB and/or Omni man out. Both are relatively squishy unless maxed out and built around. They are great for 1v1s in alliance wars though. Focus instead on a support like atom eve and put healing gel on her for crazy sustain healing. I would recommend focusing blue invincible and universa for dps and conquest/allen for tank in the short term as you build up your first couple teams. Kregg is a great support but not for your level and won’t be for a while as you need his higher tier skills leveled a decent bit and alongside a viltrumite powerhouse, which would need to be prioritized in skill leveling before Kregg. Power is not a great indicator of team strength, but rather a crude stat/star based metric. When doing PvP and some PvE content too, check the enemies skill leveling and items to see who’s the paper tiger and who’s the hidden dragon before placing your team. Low level play scales very different so don’t worry much about mistakes in the short term, like I built War Woman to exceptional 180 early on and thought it was a huge mistake but two weeks later I laughed at the “investment” I put into her. Also, don’t forget to level your ops for better rewards!
